A doped electrode is manufactured by an electrode manufacturing method. The doped electrode includes an active material doped with an alkali metal. In the electrode manufacturing method, a dope solution is brought into contact with an electrode. The electrode includes a current collector and an active material layer. The active material layer is formed on a surface of the current collector and includes the active material. The dope solution includes an alkali metal ion and flows. In the electrode manufacturing method, for example, the alkali metal is electrically doped to the active material using a counter electrode member arranged to face the electrode.

Method for manufacturing doped electrode and method for manufacturing power storage device

A power storage device includes: an electrode assembly, including a positive electrode, a separator, and a negative electrode; and an electrolyte solution. The negative electrode includes a negative electrode current collector, and a negative electrode active material layer formed on a surface of the negative electrode current collector. The negative electrode is doped with lithium. The power storage device includes first through-holes penetrating the negative electrode current collector in a thickness direction thereof. On at least one side of the negative electrode current collector, the power storage device includes second through-holes penetrating the negative electrode active material layer in a thickness direction thereof. An aperture ratio of the first through-holes on the negative electrode current collector, or an aperture ratio of the second through-holes on the negative electrode active material layer is 0.001% or higher and 1% or lower.
